Abstract
To obtain more information about the arrangement of Hind III restriction fragments in the tRNA-rRNA region of the Neurospora crassa mitochondrial (mt) DNA we have cleaved the mtDNA with Hpa I and Hind II. We could construct additional cleavage maps for these enzymes. Hybridization of rRNAs to Hind II fragments confirmed the existence of an intervening region of about 2,300 basepairs in the 24S rRNA (Hahn et al., Cell, in press). About seven tRNA genes, among which the genes for tRNA1Ser and tRNAMetM, are located in a segment of about 5,000 bp separating the 24S and 17S rRNA genes. Another cluster of 14 tRNA genes is found adjacent to the other end of the 24S gene. The genes for tRNALeu1 and tRNAMetF are located in this cluster.
